I am taking a stats class and need to do a single factor anova table with four treatments for an assignment. The instructor showed the class how to do it with minitab, and I am unsure how to proceede in R. Here is the data: I. .8 .2 1.4 .9 .9 1.0 1.0 1.1 1.4 1.2 1.0 II. 1.6 1.1 .2 1.3 1.5 .7 .5 1.3 1.3 .4 III 1.8 .3 1.1 2.0 2.8 1.5 1.3 2.9 1.7 .8 IV. 2.4 2.6 2.82.9 1.7 2.6 2.7 2.1 2.1 2.3 I have been reading the various help files and can't quite finde the right example to get started from.
Try help(aov). Basically, you will have to bring your data into a form like treatment response 1 .8 1 .2 2 1.6 2 1.1 ... ... and then use something like model <- aov(response~treatment) summary(model) This will give you a standard ANOVA table. Cheers (and good luck with the assignment) Kaspar
